Having the Labour government in power actually seems to have damaged the intellectual base of the left in Britain, judging by the popular sales of its magazines:

The circulation of the New Statesman might stand at a relatively healthy 25,000, but in the Sixties it was selling 94,000. Meanwhile, Red Pepper, launched to much fanfare 10 years ago, has failed to establish itself beyond a ghetto of environmental and social activists. Contrast this with the Spectator, where weekly sales have reached 65,000. And who would bet against that growing after the columns of free publicity provided by the sexual shenanigans of its staff and the improbable cult of Boris?
